Abstract
The present invention relates to a transportation device of a withdrawable circuit breaker, and more particularly, to a transportation device of a withdrawable circuit breaker capable of simultaneously moving right and left handles of a girder assembly for restricting movement of the transportation device or releasing a restricted state. The transportation device of a circuit breaker includes: a truck assembly on which a body of the circuit breaker is loadable; a body plate of a girder assembly installed on a front surface of the truck assembly; a pair of sliding plates slidably installed in the body plate; and a rotation plate having both sides to which leg portions of the sliding plates are rotatably coupled, respectively, wherein the rotation plate is inserted into a lead screw penetratingly-formed at a central part of the girder assembly.
